Yog lawm, Hydroxyethyl Methyl Cellulose (HEMC) feem ntau yog siv los ua kev ua haujlwm ntxiv hauv gypsum plaster formulations. Gypsum plaster, tseem hu ua plaster ntawm Paris, yog cov khoom siv dav siv hauv tsev rau sab hauv phab ntsa tiav thiab cov ntawv siv kho kom zoo nkauj. HEMC ua haujlwm ntau yam tseem ceeb hauv gypsum plaster formulations:

1. Kev tuav dej: HEMC pab khaws cov dej hauv cov gypsum plaster sib tov, ua kom cov dej kom zoo ntawm cov gypsum thiab ua kom lub sijhawm ua haujlwm ntawm plaster. Qhov no tso cai rau kom yooj yim daim ntawv thov thiab smoother finishes.
2. Txhim kho kev ua haujlwm: Los ntawm kev ua kom muaj peev xwm ua haujlwm thiab plasticity ntawm gypsum plaster mix, HEMC yooj yim dua kis, troweling, thiab tiav ntawm plaster. Qhov no ua rau lub ntsej muag zoo nkauj dua thiab zoo nkauj.
3. Txo Sagging thiab Shrinkage: HEMC txhim khu lub cohesiveness thiab thixotropic zog ntawm gypsum plaster, txo cov kev pheej hmoo ntawm sagging los yog slumping thaum lub sij hawm daim ntawv thov thiab minimizing shrinkage tawg raws li lub plaster dries.
4. Enhanced Adhesion: HEMC txhawb nqa zoo adhesion ntawm gypsum plaster rau ntau yam substrates, nrog rau cov masonry, pob zeb, drywall, thiab plaster nto. Qhov no txhim kho tag nrho daim ntawv cog lus lub zog thiab durability ntawm plaster tiav.
5. Tswj Lub Sijhawm Teeb Meem: HEMC tuaj yeem pab tswj lub sijhawm teem sijhawm ntawm gypsum plaster, tso cai rau kev hloov kho kom haum rau cov ntawv thov tshwj xeeb thiab ib puag ncig. Qhov no ua kom pom lub sijhawm ua haujlwm zoo thiab tso cai rau kev kho kom zoo ntawm plaster.
6. Txhim kho cov cuab yeej cuab tam: Kev sib koom ua ke HEMC rau hauv gypsum plaster formulations tuaj yeem txhim kho cov khoom siv ntawm cov plaster hardened, nrog rau lub zog compressive, flexural zog, thiab kev cuam tshuam.
7. Txo Cov Plua Plav thiab Crumbling: HEMC pab txo cov plua plav thiab tawg ntawm gypsum plaster nto los ntawm kev sib koom ua ke ntau dua thiab ua kom ntev rau lub plaster matrix. Qhov no ua rau lub smoother thiab ruaj khov tiav uas tsis tshua muaj kev puas tsuaj.

HEMC yog ib qho tseem ceeb ntawm kev ua tau zoo ntxiv hauv gypsum plaster formulations, muab cov txiaj ntsig xws li kev txhim kho kev ua haujlwm, dej tuav, adhesion, thiab kav ntev. Nws txoj kev siv pab txhawb rau kev tsim cov khoom zoo ntawm plaster tiav nrog cov khoom zoo dua qub thiab kev ua haujlwm zoo.
